RAINBOW: Nisha Rokubou no Shichinin

Six minors (16-17 years) answering to the nicknames of Joe, Mario, Suppon, Baremoto, Heitai, and Kyabetsu are put into a reformatory for offenses such as aggravated assault, swindling, flight, etc. Their stay in hell begins immediately. Accommodated by a doctor pedophile, they are placed under the watch of a despotic and brutal crew. Cellmates with a certain Sakuragi (called Anchan), the tension rises between the band of buddies and their new "friend." A brawl breaks out, and our six prisoners are done rossés by the mysterious young man, thanks to his boxing talent.
